AQUATIC VEHICLE Filed Aug. 51, 1929 Patented Dec. 1, 1931 UNITED STATES JEAN REHBOCK, or wnsnnreroiv, nrs rftrc'r AQUATIC rem i i Application filed August 31, 1929, Serial No;

This invention relates to aquatic craft and more particularly to sucha device designed to rest lightly upon the surface of the water and to bepropelled at a high speed on said surface.

It has for its object the provision of means for sustaining the craft on the water whlch, while insuring to it all the buoyancy desirable when at rest, opposes a minimum of resistance to the forward movement of the craft on the water. A further object of the invention is to combine with a craft of this kind which lightly rests upon the water, a propelling means.

Like reference numerals indicate like parts throughout the several figures of the drawings in which:

Fig. l is the side elevation of the embodied invention,

Fig. 2 is a plan,

Fig. 3 is the front elevation of a modified form of the invention, and

Fig. 4 is an elevation thereof.

The invention may be embodied in a mul- 25 tiplic-ity of devices, some of which may be sea-going craft and others small enough to be used as pleasure craft upon inland lakes, the underlying thought, however, being the fact that it is for use in connection with-J rough water.

In the drawings the numeral 10 represents the body of an aquatic craft while 11 and 12 represent ariel propellers for driving the craft. The body is mounted in a sustaining frame shown as comprising side beams 13 and 14 at the ends of which are mounted buoyant rollers 15 and 16. Between the ends the body is supported pivotally upon an axle 17 and to either side of the body are additional buoyant rollers 18 and 19.

Vhile a sustaining system of conventional elements is shown it will be appreciated that this system may be formed of other elements and arranged in a different manner. The important point is that the craft is constituted by a body which is swingingly or pivot ally mounted ina supporting or sustaining frame and that the body is provided with propelling means either ariel or marine while 53 the supporting system is designed to mainainl heEr r m r i i r d vh l a but which will 'be substantially lifted 111-0 389,824,:and in mm September 19,{1928;

The sustaining means inthis instance is a single roller 25 atthe frontof theplaiie ep on which the plane is .journaled through; the

legs 26 and 26. The .rearroller 27iis utilized .to support the plane at restso that the propeller will not touch either the vgroundior 1 the water whileit is at rest. l The. numeral .28 representspneum'atic tires which are protvided in order. that the plane. may be-driven' into a, hanger orsruualong the earth. @It

will.beappreciated, however, that while the plane is traveling over; the surface, of 210 fwater. the roller 27 voccl lpiesatgiall lti h i ,elevatednposition about thenwatefr,

The operation of. both forms willbe under stood from a description .oflthe operatiomof the plane in, Figure i.1 Thenfthecraft gigg ng;

rest the forward 'roller 25.,rests1inf'tl1ewater r in substantially the depthindicated the dotted lines in said figure, The line A Ain said 1 figure represents the. general level of the water. .The ruui pe B -B' in that' figure represents the plane as it rides the wave and it will be appreciated that as the craft is in motion the roller 25 will be lifted from'the water so that only its surface will be in contact with the surface of the water. In fact, due g? to the revolving of the rollerthere is a suction of air under the roller between it and the surface of the water as represented by the arrowed lines 29 and this body or film of air will act somewhat as a lubricant reducing s the friction between the roller and the water to a minimum. v a

It will be appreciated that by this arrangement of buoyant element and craft body that the craft is always in acorrect line for driv- .5-9. ing; that it may be lifted or lowered by the water but will never be out of' line for correct driving. It reduces to a minimum the displacement or. the throwing of water.- The effect difiers from that produced in the ord dinary glider plane where the buoyancy is maintained by virtue of the inclination of the support to the plane of the water.

The aquatic wheels 15, 16 and 25 may be ,3 formed in a number of ways and of a Variety of materials, Their surface may be smooth or they may carry rough elements to promote v therolling'motion. They may be made hol low and if desired divided into air-tightcomo partments and they may be. filled with cork or similar substance. If they are hollow they may be utilized as reservoirs for fuel, communication with them being through the axle. Their number and disposition on a" 15 given craft may vary and will necessarily varyac'cording to the different types of craft. v They may be even grouped and mounted in the form of rigid trains or flexible caterpillars, or they may be formed in trains and V a} coupled or not, as desired.

, In my prior Frenchand German-applications for patents referred to in the oath to this application the rollers have been shown in .the' form of spheres, cylinders, barrel- 25 shaped, double cones, etc. -What is; claimed is: p

' 1. In an aquaticcraft, a craft body, a buoyancy system in which said craft body is swingingly mounted, said systemcomprising '30 rollers revolubly mounted herein and designed to contact in'the movement of the craft withthe surface of the water and to cause a film of air to beentrapped between them and the water surface, and means independent of 8]! the buoyancy system for propelling the'craft at 'a'high speed over the surfaceof the water.

2. In'an aqua-tic craft,a= craft bod a. buoyancy system in which said craft. body is swingin ly mounted, a driving means for 40 said" bo y, the system comprising elements which'are' movable under the influence of the water surfaice,.said movement being free of any movement of the body or driving means.
